Sidr is very prompt and knowledgeable and has done an excellent job handling our Colorado Sales tax filings which was such an impossibly difficult process for me previously! Definitely worth it! So happy with the Shopify integration. It has made life much better!

5 stars aren’t enough! Excellent and professional service. We are in different countries, and whenever I email them， even during their off-hours, they still reply and never leave me waiting because of the time difference. I really appreciate their help.

So far we love Sidr. Registering in different states is really confusing and comes in staggered long timelines. Their chat and staff patiently guide you through. They're wonderful

They don’t just file your sales tax—they become a real support partner for your business. Their team consistently goes above and beyond, offering fast, detailed, and genuinely valuable guidance over chat. The quality of help they provide easily feels like a consulting service, and they deliver it with patience and clarity every time.

AVOID! intalled the app, never used it, after 4 months noticed over $1,000 in billings paid for them. support declined to do anything about it. be cautious

One of the best sales tax filing providers. Despite of filing your sales tax, they give bunch of help over the chat which worth of 1000$ or more!

Sidr has been SO helpful and easy for managing all of our sales tax - the team are also amazing, I've never experienced customer service like this before! Highly recommend!

Sidr company helped me file my sales tax the same day I reached out. Their team responded very quickly and made the whole process simple and easy to understand. Compared to other services I’ve tried, their pricing is very affordable, and the experience was way smoother. Highly recommend to any store owner looking for fast and reliable tax filing help!

Out of all the apps I've used, this is by far the best. They make tax compliance easy. The customer service is the best I've experienced. Kevin has saved me tons of time and money. Thank you! Melanie, PF Wonder Salve

I read all of the outstanding reviews of SIDR tax and decided to work with them. As I worked to setup my sales tax account with SIDR, they were with me in the setup answering questions and making the setup very easy. We sell nationwide & their system tracks sales to all states & informed me as I reached states nexus. SIDR has filed three quarters for me on time, ensuring payments are made, my level of confidence in SIDR couldn't be higher not to mention my sales tax stress has ended as I am in capable hands with SIDR, couldn't recommend them more. Thank you
